I decided to save myself the heat and the noise of my mining rig. I built a small box to put my mining rig on the deck.

The box have a good fan (20W) to take air from under the box and direct it on the cards. Hot air escape from 2 vents at the other end of the box. The router inside the box is a client to my other router in the house. Takes more space than a wifi card or usb but it was free .

I tested the box during the worst storm in a long time. Not a single trace of humidity in the box.

So far the computer seems to enjoy being outside especially during the night when it's colder. The box is always shaded from the sun.

condensating water happens, if air can't hold the humidity anymore. This happens for example if warm air gets colder, cause warm air can take more water. So if humid air gets into that box where it gets warmer no condensation happens.
